Question
Sona wants to study and compare the accelerations of two uniformly accelerating bodies. Which of the following should she do?
- Plot a position-time graph
- Plot a velocity-time graph
- Both 1 and 2
- Neither 1 nor 2
Hint:
Slope of velocity time graph represents acceleration.
The correct answer is: Plot a velocity-time graph
- Sona should plot a velocity-time graph. As the slope in velocity-time graph represents the acceleration of a body. So, the value of a slope at a particular time represents the acceleration of body at that instant.
- Whereas slope in position-time graph represents velocity.
